Sapphire Plug-ins for Autodesk: FilmEffect

FilmEffect

Provides a physically accurate model of film exposure
and processing to make your video footage look like it was shot on
particular film stocks. It can remove field artifacts, perform
color correction for specific film types, add film grain, and apply
glow or soft focus effects. The color correction and grain can be
selectively disabled using the Scale CC and Grain Amp parameters.

Inputs:

Source:
The clip to be processed.

Parameters:

Load Preset:
Push-button
.
Brings up the Preset Browser to browse all available presets for this effect.

Save Preset:
Push-button
.
Brings up the Preset Save dialog to save a preset for this effect.

Scale CC:
Default:
1,
Range:
0 or greater.
Scales the amount of color correction performed due to
the film types, gamma values, and exposure values. Set to 0 to
disable color correction. If you increase this above 1.0 it
exaggerates the color correction, which normally increases the
contrast.

Input Gamma:
Default:
2.2,
Range:
0.1 or greater.
The gamma that your original clip was shot for. For
video this is normally 2.2; for synthetic computer graphics it may
be less.

Scale Brights:
Default:
1,
Range:
0 or greater.
Scales the bright areas of the final result after
the other color correction, glow, and grain are applied. (This
parameter is not affected by Scale CC.)

Offset Darks:
Default:
0,
Range:
any.
Adds this gray value to the darker regions of the
final result after the other color correction, glow, and grain are
applied. This can be negative to increase contrast. (This
parameter is not affected by Scale CC.)

Grain Amp:
Default:
1,
Range:
0 or greater.
Scales the amplitude of the film grain that is added to
the result. Set this to 0 to disable all grain.

Grain Blur:
Default:
0,
Range:
0 or greater.
The grain is smoothed by this amount. Increase for
coarser grain.

Grain Hold:
Popup menu, Default: Frame
.
Indicates how often a new grain pattern should be
generated. You will probably only notice a difference between these
options if Grain Blur is positive to make the grain size larger than
one pixel.

Field:
holds the grain pattern for one field.

Frame:
holds the grain pattern for one frame (2
fields).

3:2 Pulldown at 0:
holds the grain in a 3:2 pulldown
pattern with the first pulldown frame at 0. These options are
appropriate if your clip was created at 24 fps but is now in 30 fps
pulldown form. They will not make sense if your clip is 24P. A 3:2
pulldown pattern repeats every 5 frames, so if frame 1:00:23 is the
first frame with field artifacts after three normal frames, then you
should specify 3 as the first pulldown frame.

3:2 Pulldown at 1:
holds the grain in a 3:2 pulldown
pattern with the first pulldown frame at 1.

3:2 Pulldown at 2:
holds the grain in a 3:2 pulldown
pattern with the first pulldown frame at 2.

3:2 Pulldown at 3:
holds the grain in a 3:2 pulldown
pattern with the first pulldown frame at 3.

3:2 Pulldown at 4:
holds the grain in a 3:2 pulldown
pattern with the first pulldown frame at 4.

Glow Brightness:
Default:
0,
Range:
0 or greater.
If positive, the image is combined with a blurred
version of itself to give a glowing look. Increase for a brighter
glow.

Glow Soft Focus:
Default:
0,
Range:
0 to 1.
If positive, the image is mixed with a blurred
version of itself to give a soft focus look. The effect of this
parameter is similar to Glow Brightness, but this does not brighten
the overall result. Increase this to mix in more of the blurred
version and less of the original. If this is 1 and Glow Brightness
is 0 you will get only the blurred version.

Glow Width:
Default:
0.5,
Range:
0 or greater.
The width of the blur used by the glow and/or soft focus.

Fields:
Popup menu, Default: As Is
.
Allows removing field artifacts from the input clip.
This is useful if you want the clip to look like it was shot on
frames instead of fields. You can show a single field, merge the
two together, or simulate a 3:2 pulldown stutter pattern.

As Is:
leaves the fields unchanged.

Keep Lower Only:
shows the lower field only, removes the upper field.

Keep Upper Only:
shows the upper field only, removes the lower field.

Merge Fields:
blends both fields together to remove interlacing artifacts.

3:2 Stutter at 0:
Simulates a temporal stutter effect as if
the clip had been transferred from 24P to NSTC video using 3:2
pulldown, with the first pulldown frame at 0. If you are using this
option with non-zero Grain Blur, you may want to also set Grain Hold to
the corresponding value.

3:2 Stutter at 1:
Simulates a 3:2 pulldown effect
with the first pulldown frame at 1.

3:2 Stutter at 2:
Simulates a 3:2 pulldown effect
with the first pulldown frame at 2.

3:2 Stutter at 3:
Simulates a 3:2 pulldown effect
with the first pulldown frame at 3.

3:2 Stutter at 4:
Simulates a 3:2 pulldown effect
with the first pulldown frame at 4.

Field Dominance:
Popup menu, Default: 1
.
Specifies which field should come first in time
when simulating 3:2 pulldown patterns. This is only used if a 3:2 stutter
option is selected in the Fields and/or the Grain Hold options.

1:
Field 1 occurs first in time, then field 2.

2:
Field 2 occurs first in time, then field 1.

Params2:

Grain Amp Darks:
Default:
0.2,
Range:
0 or greater.
The relative amount of grain applied to the darkest
regions of the image, per channel. This defaults to less than 1.0
because dark areas usually have less grain than midtones.

GrainAmpBrights:
Default:
0,
Range:
0 or greater.
The relative amount of grain applied to the
brightest regions of the image, per channel. This defaults to zero
because bright areas usually have less grain than midtones. Note
that highly saturated colors can be affected by both Grain Amp Darks
and Grain Amp Brights because they are dark in some color channels
and bright in others.

Midtone Pos R:
Default:
0.5,
Range:
0 to 1.
The position of the midtones in the red channel
that will normally receive the maximum amount of grain. The red
grain amplitude is interpolated from Grain Amp Darks at black, up to
1.0 at this midtone position, then down to Grain Amp Brights at
white. This whole curve is then scaled by the Grain Amp Red
parameter.

Midtone Pos G:
Default:
0.5,
Range:
0 to 1.
The position of the midtones in the green channel
that will normally receive the maximum amount of grain. The green
grain amplitude is interpolated from Grain Amp Darks at black, up to
1.0 at this midtone position, then down to Grain Amp Brights at
white. This whole curve is then scaled by the Grain Amp Green
parameter.

Midtone Pos B:
Default:
0.5,
Range:
0 to 1.
The position of the midtones in the blue channel
that will normally receive the maximum amount of grain. The blue
grain amplitude is interpolated from Grain Amp Darks at black, up to
1.0 at this midtone position, then down to Grain Amp Brights at
white. This whole curve is then scaled by the Grain Amp Blue
parameter.

Grain Amp Blue:
Default:
1.6,
Range:
0 or greater.
Scales the blue grain amplitude. Note that grain is
added and subtracted from the image, so for example, increasing
Grain Amp Blue will amplify both the blue and yellow speckles.

Grain Mono:
Check-box, Default:
off.
When enabled, the same grain pattern is used for the
red, green, and blue channels. To make truly monochrome grain you
should also set Grain Amp Red/Green/Blue equal to each other, make
sure Midtone Pos Red/Green/Blue are equal, and if GrainBlur is
positive also set Grain Blur Red/Green/Blue equal

Grain Seed:
Default:
0.123,
Range:
0 or greater.
Initializes the random number generator for the grain
generation. The actual seed value is not significant, but different
seeds give different grain patterns and the same value should give a
repeatable pattern.

Params3:

Vignette Dark:
Default:
0,
Range:
0 to 1.
Vignetting is darkening of the image towards the
corners and sides of the image. This parameter controls how much
the outer corners of the screen should be darkened (vignetted). 0
gives no vignetting, 1 gives maximum darkening.

Vignt Radius:
Default:
1,
Range:
0 or greater.
Distance from the center to apply the vignette.

Blur Mocha:
Default:
0,
Range:
0 or greater,
Shared
.
Blurs the Mocha Mask by this amount before using.
This can be used to soften the edges or quantization artifacts of
the mask, and smooth out the time displacements.
